and could lead to electrocution.
DO AT YOUR OWN RISK
Loud ticking sound on Channel A, sounded like the Switch mode power supply not starting up?
Circuit diagram and component datasheets available on a internet search
faults
Output Mosfets (IRFS23N15DPbF) T10, T11, T12 and T13, read as open circuit, little unusual as most Mofet's go short.
Replaced with IRFS4227PbF
C69 - 1uf 250v cap had gone all but short 2ohm
IC15 (IRS20955(S)PbF) faulty
Replaced IC15 and IC16 with IRS20957S
